To all wiz-om' t may concern.'

Be it known that l, WILLIAM RArMoND DUNQAN, a citizen of the United States, and i alresident of Chicago, @ook County, Illinois,

This' invention contemplates certain im-l provements on the marking` device disclosed vin' the application of l/Villiam H. Wade No. -l81,763, iiled July 1,1921, and contemplates theV provision ot Astationarymeans for supporting the 'phonograph record during the marking thereof, having stationary means `fior engaging the edges around the center hole ot' the record, 'and tor supporting and guiding the means for printing or making the impression on the record, as will hereinafter more fully appear. I

It is also an object to provide certain detailsand features oic construction tending to increase the general efficiency and desirability of a marking device ot this particular character.

'llo this and other useful ends the inventiony consists in mattershereinai'ter set forth and claimed and. shown in the accompanying drawings in which Figure 1 is a plan of a marking device embodying the principles et the invention, showing the phonograph disc record in position ior the marking operation tliereon.

Figure 2 is a vertical section on 2-2 in lligure 1.

lfigure is a fragmentary view olY a portion of the record, showing the center portion thereof after the marking device has performed the desired printing or marking operation thereon.

As thus illustrated, the invention comprises a suitable base 1 at the center of which is a post or upright member 2 for engaging the center hole 3 of the record 4L, which latter has a smooth surface 5, as usual, between the center hole and the grooves of the record. Cloth or telt or other material G is preferably applied to the top of the base 1 to provide a tlat and yielding support for the underside of the record during the operation of printing or marking thereon. The. marking means, as shown, include a disc-like body 7 provided `with an upstanding handle 8, the lower portion of which latter is bored vertically to provide a guide 9 to receive the cenkcavity occupied by the spring.

terl po'st 2 previously mentioned. rllhe handle contains a coil 'spring' 10 which bears against the movable abutment l1, tne latter resting against a shoulder 12 formed inside oil the handle, at the upper end ot the bore 9, and a plug 13 is inserted in the upper end of the Thus the spring is retained in thehandle and is compressed by ythe upward movement yot the abutment 11, when the latter engages the top of the post 2, and when the handle is pressed downward to move 'the printing means 142 (the printing means maybe a rubber stamp or die of anyV suitable character) into engagement with the upper surface of the phonograph record, thereby to print an ad-. vertisement thereon, as shown in Figure 3 ot the drawings. TWhen the handle isreleased, thefspring 10 willexpand and raise the printing means a distance above the disc record, the normal position being substantially as shown in Figure 2 of the drawings.V fin arrow 15 or other suitable means is provided on top 'of the disc 7 to enable the user to turn or rotate the handle and disc 7 until the printing -meansare in proper position for the impression on therecord.

The method of using the device is as Yfollows: The handle 8 and the disc '.7 are lifted upward and disengaged rtrom the post 2, and the record el1 is then placedin position as shown, by insering the post 2 upwardly through the hole 3 in the center oi the disc record. After the disc 7 and the record 4l are relatively adjusted, by rotation of the handle until the arrow 15 points in the desired direction., the handle is then pressed downward and the -printingmeans 14 are thus brought into engagement with the smooth upper surface ot the phonograph record, it being understood that ink or other suitable substance is carried by the printing means to produce theA desired result. To apply the ink or other substance the handle 8 canbe pulled upwardly and the bottom of' the disc 7 can be pressed against an inkpad in the manner of an ordinary rubber stamp. The printing means are then returned to the post2, after the phonograph record is in position, and the device is then in condition for operation. Thus the lmeans for properly positioning the phonograph rec'- kord are stationary torni astationary guide for the movable printing or marking means. 'lt Will be seen'thatthe impression made by the marking means is in the smooth space between the usual label on the record and the area covered by the grooves. in other Words, a round label is usually applied at the center of the record, around the center hole, but a smooth space is left between the outer edges of this label and the said area of the grooves of the record, and the printing or marking is preferably done on this smooth exposed surface of the record,

although it may be placed elsewhere with? out departing from the scope and spirit of the invention.

What l `claim as my invention is-v l. ln means for marking a phonograph disc record having record grooves and a smooth area, marking means disposed in position to' operate upon the smooth area,

tered thereon by said post.

3. A structure as specified in claim l, comprising a spring` lor vyieldingly supporting the ysaid marking means on the upper end of said {iost,said marking means being adapted to be removed from said post to permit the latter to enter the center hole of the disc record.

4l. A structure as specified in claim l, said. marking means comprising a body with ksaid handle.

5. Means 'for marking a phonograph record, comprising marking means disposed in position to niark the record in the annun lar space ordinarily provided between the central label and' the `grooves oi a disc record, and means ior engaging the disc toposition the latter and said marking means relatively to each other, thereby to ensure accurate placement, of the iiiarlring in said annular space, characterized bythis, to-Wit: That said means for engaging .the disc include a stationary post adapted to pass through the center hole of the disc, and forming a guide t'or the movement of said marking means, the latter being removable from said post to permit the insertion,thereoiC through the center hole of the disc record.

G. A structure as specified in ela-iml 5, comprising means for yieldingly supporting the marking means on the upper vend of saidpost,the latterbeing vertically disposed, and said-marking means being rotatable on said post to properly position the engaging portion thereof relatively-to the disc record.

7. A structure as speciied in claim 5, said post being vertically disposed and having a base at its lower end to form a support 'for the disc record, whereby said marking means are movable up and down on said post, being removable from the upper end ofthe post to permit the placing or' the disc record on said base. i 1
